bug: g_ctrlp_extensons execution priority is too low

[q962]

ctrlp.vim/autoload/ctrlp.vim

Lines 231 to 233 in 8b4a952

	for [ke, va] in items(s:opts)
	let {va[0]} = exists(s:pref.ke) ? {s:pref.ke} : va[1]
	endfo

What is obtained here is s:usrign, but the filtering function is realized through a g:ctrlp_custom_ignore (alias s:usrign).

The autoignore.vim extension modifies g:ctrlp_custom_ignore

ctrlp.vim/autoload/ctrlp.vim

Lines 274 to 279 in 8b4a952

	" Extensions
	if !( exists('extensions') && extensions == s:extensions )
	for each in s:extensions
	exe 'ru autoload/ctrlp/'.each.'.vim'
	endfo
	en

s:usrign has already used the default value, and it is too late to wait for autoignore.vim to modify g:ctrlp_custom_ignore.

To call the autoignore function requires three operations, which is too cumbersome

What happens if you increase the execution priority of an extension?
